HEATING ivrnnns non INGUBATORS} I 1 To all whom it may concern:

Be it known that I, JosEPH SELL, a citizen of the United States, residing at'Rusln center, in the county of Bush, State of Kansas, have invented a new and useful Heating Means for Incubators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improved heat ing means for incubators, and an object of the invention is to provide a cylindrical member extending through an incubator, and into which member the heat is projected, there being a heater or lamp below the cylindrical member and extending thereinto, in combination with a damper over the cylindrical member, which is automatically regulated by the heat in vthe incubator, owing to the heat acting upon, a thermostatic device in the incubator.

Another object of the invention is to provide means for adjusting the lamp or heater, so that more or less of the heat may be projected into the cylindrical member.

Another object of the invention is the provision of a water container adjacent the cylindrical member, so as to render the heat in the incubator moist instead of dry.

Another object of the invention is to provide the lower part of the water container with the drain cook or faucet, for draining the water container.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a vertical sectional view through an incubator, showing the improved heating means applied thereto.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a detail perspective view of an angular bracket, showing the lamp holder or support adjustably mounted thereon.

Fig. 4 is a plan view of the holderor support for the lamp or heater, showing the slotted arm of the angular bracket in section.

Referring to the drawings 1 designates a conventional form of incubator having a chamber 2 for the eggs, and supported upon Specification of Letters Patent. Patented Aug. Application filed August 19, 1,915. Serial No. 46,295. i

her 7 forming a heating chamber 8. f'lhe flange 9 at the upper end of the member 7 prevents downward movement of the member. A circular ring 10 is threaded at ll to the lower end of the cylindiicalmehiber 7.-

so that the part 12 of said ringengaging the bottom of the incubator will reventupward" movement of the cylindricalmeinber "Se cured at 13 to the bottom of the incubator is an angular bracket 14' having a down wardly extending slotted arm15. -A-lam'p holder or support consisting, of an annular ring 17 and a bracket part 18 is provided.

The bracket part has an elongated tongue 19, which fits into the slot of'the arm 15,", there being a plate 20 secured by screws; 21 (which pass through the, slots oft-he ,arm

15 and into the tongue 19) to the bracket part 18, wlth the arm 15 between the plate 20 and said bracket part 18. It is to be observed that by loosening the screws 21, the

support 16 may be raised and lowered. By

lowering the support 16 toward the lower-'1 part of the arm 15, the upper portion or top of the lamp or heater 22 is arranged below the cylindrical member 7, thereby decreasing the heating efi'ect of the lamp. Riveted A at 23 to the side of the cylindrical member 7 is a water container 2 1 constructed of any suitable material having a conical bottom 25 and a contracted extension 26 provided with an outlet orifice 27. The contracted extension has a transversely disposed drain cook or valve 28, for drawing oif the water in sa1d contalner. In the walls of the cylindrical member 7 and the container are registering openings 29, so that some of the heat may pass into the container, to assist in heat ing the water, which is also heated owing to' the container being secured to the side of the cylindrical member 7. Pivoted to a post on'the top of the incubator, asat 30, is

a lever 31 having a damper 32, cooperating with the upper open end of the cylindrical member 7. When the damper 32 is in contact with the flange 9 of the cylindrical member 7 the heat is confined in the cylindrical member 7, except ng that Whlch passes through the openings 29 into the water container, thereby keeping the container and the water therein well heated. Pivoted' at 33 to a second post on top ofthe ineuba tor is a lever 34, one end of which is pivoted at 35 to the short arm of the lever 31', the other end of the lever 84 being pivoted at 36 to a link 37, which in turn is connected to a thermostat at 38, supported on a bracket 39 inside the chamber 2 of the incubator. Vhen the temperature in the chamber 2 rises to a certain degree this thermostat expands, lifting the damper 32, thereby decreasing the heating effect, and as the thermostat 38 contracts, owing to the temperature descreasing in the chamber 2, the damper 32 will close, thereby maintaining the temperature in the chamber 2 substantially uniform.

The invention having been set forth, what is claimed as new and useful is In an incubator having an incubator chamber, a heating apparatus comprising-awater container arranged vertically centrally in said chamber and having its upper and lower ends connected in the upper and lower walls of said chamber, said container having its upper end open and its lower end provided with draining means, an air heating tube having its upper and lower ends open, said upper and lower ends of said tube projecting through the upper and lower walls of said chamber, the upper end of said heating tube having a flange cooperating Copies of this patent may be obtained for with the upper Wall of the chamber, means for detachably connecting the lower end of the heating tube to the lower wall of the incubator chamber, the wall of the tube being in contact with the wall of the water container, both the container and the heating tube being removable, said adjacent walls of the tube and container having registering openings substantially midway their contacting surfaces, whereby the heat from said tube may pass through said openings into the container and over the surface of the water, a heating element adjustably supported below said chamber, for adjustment into said air heating tube, and automatic means cooperating with the upper open end of said air heating tube for controlling the heat from the heating element, whereby the heated air may be allowed to escape from the upper end of the tube or caused to pass through said openings and over the surface of the water in the container.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
